'mxwasavbz end of the tile during transit from feed rests when in the pocket, and against which the tile is pressed during measurement as hereinafter set forth.

Foreach set of coinciding tile pockets 7), formed in the forwarding disks B, B, I

provide separate feeling and indicating Interposed between the inner side of the' mechanism, like unto that shown in the drawings, and here described, the others being omitted for briefness and simplicity of illustration. Vith this understanding, E, represents a rock lever fulcrumed on bracket lugs 6 ,1 projecting from the outer side of the forwarding disk B. The upper arm 0, of this rock lever .E, performs the function of a feeler, being formed with a finger e, for contact with the end of the tile 'I presented for measurement "Pivotally attached to the feeler arm'e, is a feeler rod F, mounted in bearings in the forwarding disks B, B, in such manner as to be capable of longitudinal movement.

forwarding disk B and an adjustable rest f, on the feeler rod F is a coiled spring f encircling said rod, the adjustment ,of the rest f, affording means for regulating the tension or pressure to be exerted by the feeler arm 6, against the tile during measure ment, it'being understood that the tile during the operation is pressed against the gage rests 6 on the other forwarding disk B.

Upon the opposite end of the feeler rod F, beyond the disk B, is mounted a roller f This roller f protrudes into the path of a stationary cam G, formed and arranged to contact with the roller 7, in the interval j between the discharge of a measured tile onto the chute H and the taking up of another tile from the chute A. In other words the cam G, forces back the feeler arm 7 e, against the resistance of the spring 7''", to

receive or discharge a tile, but does not act on the roller f between the take up and discharge, leaving the spring free to press the feeler arm 0, and finger 0, against the T chute A, to discharge chute H, it being undeistood that the rotation of the forwarding disks, feeling mechanism &c., is continuous during operation.

The lower or signal arm 6 of the rock lever E, carries an electric circuit closer c connected by a conductor 6', passing through.

the hollow end 0,-of the shaft G, with the commutator bars I, insulated on the end of the shaft C.- v

" When the roller f leaves the cam G,

allowing the spring f, to rock the lever E to feel'the .tile T, the circuit closer 0 on the-signal arm 6?, of the'said lever E, contacts successively '(according to the length of the tile) with a series of contact points consisting preferably of screws 70', 70 71 -Fig. I mounted on independent spring tongues 71'! is, k, is, attached to an shaft C. The spring tongues 7c, 70 is,

is, are connected electrically and individually by conductors m, m m m, passing through the hollow end 0, of the shaft 0, with collector rings n, n a n, mounted upon the end of the shaft C, but insulated therefrom and from each other.

The contact screws are so adjusted with relation to each other that the circuit closer e' ,-on the signal arm E, will first contact with contact screw is, representing the maximum length'of tile; then successively with the other contact screws 70 I0 73*, according to the variations in the length of the tile,the elasticity of the spring tongues 7c, is, is, is, allowing the contact screws to adapt themselves to the variations in length between maximum and minimum length of tile. For instance if the tile being measured is less than of maximum length, contact screw is, and its tongue is", will yield to admit of the contact. of the circuit closer 6 on the signal arm with the contact screw 70 and so on for succeeding degrees of shortness.

The operation of measuring and indicating the several lengths of tile passing through the apparatus will be clearly understood by reference to Fig. 5, in which the circuits, and connections are represented diagrammatically with relation to the operative parts. In said Fig. 5, S, 3*, S S represent electromagnetic indicators, or equivalent electric signals of any kind, interposed in the several circuits, of which the battery Z, or source of electricity, forms trically connected by the wires 5', s .9 s,

with the electric indicating devices S, S S S, which latter are in turn electrically connected by the wires 8', s, 8 s, with the main circuit line 71, having the brush. 2', for contacting with the commutator bar I, as the shaft C, rotates.

It is obvious that the circuit closer 0 will' first encounter the screw 70, on the spring tongue. k, and that the brush 2, coming in contact with the commutator bar I, the circuit 7c, 70, m, a, it", s, 8, if, i, I, 6 and a will be closed, thereby actuating the electric indicator S. If the circuit closer e advances further it will ergcdunter the screw 72 on the spring tongue 70, (the tongue 70', yielding) thereby closing the circuit 70 is, m,,

' electric signal S; and so on continuously with an electric, circuit closer, automatically rocking to the end of the series in the case of the shorter tile measured, thus completing all the circuits, which are closed by the contactplate a and causing all the electric indicators S, S S, S, to act. Hence, the longest tile operates only indicator S, the nextshorter only S, and S and so on, while the shortest tile operates all the indicaters. As before intimated this system of connections and contacts between the collector rings 11,, n a n, and contact points is, 10 is, k, is duplicated for each feeler E, employed; and each contact plate 0, is connected with its own particular commutator bar I.
